Fun - Develop Tic Tac Toe game in Oracle ADF/Java

Tic Tac Toe or Naughty Cross is a paper-pencil game for two players and simple in  concept.
I have developed a application on ADF, using JSF page and unbounded adfc-config.xml .
There is nothing to explain, see the sample application at bottom of this post

• Tic Tac Toe game has 9 square to enter values 0 or X, so for that i have used 9 buttons and images of 0 and X

• And create a managed bean for all nine buttons, to execute proper conditions for each move
   
• See managed bean code and conditions for player's move(only Java Code is needed to do this)

Using JQuery in Oracle ADF

JQuery is advance javascript library to support client side scripting of HTML, it is free and Opensource software licensed under MIT.
Jquery is designed to make it easier to create animations, enhance look feel of component, smooth navigation.
Read about Jquery- http://jquery.com/ , https://jquery.org/
here i am showing you, how to add Jquery in oracle ADF application.

• First add Jquery library to your fusion web application, download library file Download
• Add this file to javascript resources, see image
  
• Now create a javascript(Jquery) file to change color of af:inputText, here is javascript code is given






function changeColor() {
    if ($("input[name=it1]").val() != null) {
       if (($("input[name=it1]").val().length > 0) && ($("input[name=it1]").val().length < 3)) {
            $("input[name=it1]").css("color", "magenta");
        }
      else if (($("input[name=it1]").val().length > 3) && ($("input[name=it1]").val().length < 6)) {
            $("input[name=it1]").css("color", "red");
        }
        else if (($("input[name=it1]").val().length >= 6) && ($("input[name=it1]").val().length < 9)) {
            $("input[name=it1]").css("color", "yellow");
        }
         else if (($("input[name=it1]").val().length >= 9) && ($("input[name=it1]").val().length < 12)) {
            $("input[name=it1]").css("color", "maroon");
        }
         else if (($("input[name=it1]").val().length >= 12) && ($("input[name=it1]").val().length < 15)) {
            $("input[name=it1]").css("color", "teal");
        }
         else if (($("input[name=it1]").val().length >= 15) && ($("input[name=it1]").val().length < 18)) {
            $("input[name=it1]").css("color", "blue");
        }
        else {
            $("input[name=it1]").css("color", "green");
        }
    }
}



• Now create a jspx page , and call this JS file as a resource in jspx page, and also add Jquery Lib to jspx page as Resource
  
  
  
  
• Now add a input text in page, and call javascript resource using af:clientListener
  


• See the code of jspx page-



<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1" xmlns:f="http://java.sun.com/jsf/core"
          xmlns:af="http://xmlns.oracle.com/adf/faces/rich">
    <jsp:directive.page contentType="text/html;charset=UTF-8"/>
    <f:view>
        <af:document title="JqueryADF.jspx" id="d1">
         <af:resource type="javascript" source="/javascript/libs/jquery-1.4.4.js"/>
         <af:resource type="javascript" source="/resources/js/inputText.js"/>
            <af:form id="f1">
            <af:inputText label="Chck JQ" id="it1" contentStyle="font-weight:bold;">
                        <af:clientListener type="keyDown" method="changeColor"/>
                    </af:inputText>
            
            </af:form>
        </af:document>
    </f:view>
</jsp:root>



• Now Run this application and enter value in input text field and see how color is changing with length
  
  
  
  
  
  
  
  
  
  
  
  
  
• You can use this , with your password field, for any kind of alert, to make 'Find and Enter' games
• One more thing , it is difficult to use Jquery with pagefragments because in page fragments component id's are like :t1:cb1, r1:t1:it2. and jquery does not support ':' so you can easily use this with .jspx page

Generate Barcode Image in Oracle ADF using OnBarcode API

In this tutorial we will learn how to generate Barcode Image for any Number(Barcode) in ADF using OnBarcode API, this API provides barcode SDK(Software Development Kit) to generate Barcode. This is paid.
You can get it from http://www.onbarcode.com/  , click on Download to get barcode SDK.

• Now create a fusion web application and add barcode.jar to project libraries, you will get this JAR , when you download SDK
• Good thing about this API is that it is very simple to use, not much code required to generate a simple barcode image
• You can generate multiple type of Barcode as Code 39, Code 128, EAN-8, EAN-13, UPC-A, UPC-E
• Suppose i have to generate a Code128 type of Barcode for any barcode number, so for this write this simple code and you are done






Code128 barcode = new Code128();

barcode.setData("122322311");
barcode.drawBarcode();

Set and Get Value from Taskflow parameter (pageFlowScope variable) from Managed Bean- ADF

Hello All

This post is about getting and setting value in taskFlow parameter using Java Code so for that we have created a application with bounded taskFlow

Let's see how to do this -

We have bounded taskflow having Input Parameter defined in it named GLBL_PARAM_TEST

and we have to set its value from managed bean.
this is very simple -see how to do that

• Get pageFlowScope Map and put parameter 's value in it



        Map paramMap = RequestContext.getCurrentInstance().getPageFlowScope();
        paramMap.put("GLBL_PARAM_TEST", "Ashish"); 



• And get Value from taskFlow parameter in managed bean





    public String resolvEl(String data){
               FacesContext fc = FacesContext.getCurrentInstance();
               Application app = fc.getApplication();
               ExpressionFactory elFactory = app.getExpressionFactory();
               ELContext elContext = fc.getELContext();
               ValueExpression valueExp = elFactory.createValueExpression(elContext, data, Object.class);
               String Message=valueExp.getValue(elContext).toString();
               return Message;
             }


String param=resolvEl("#{pageFlowScope.GLBL_PARAM_TEST}");

Beauty of ADF- Taskflow, Difference b/w Facelets and JSP XML fragments in bounded taskflow

Oracle ADF framework support modular architecture for enterprize application development. Multiple small module can be bound together to form a large module .
The greatest advantage of ADF controller over core JSF navigation model is that it splits a single bulky module to multiple reusable and interconnected modules known as Taskflows.

i am not going deeper in Taskflows as every ADF developer know about it ,so the important part is page fragment.

• When  we create taskflow as bounded taskflow , and check it to create fragment in taskflow.

• Now when we create pagefragment in bounded taskflow, there is 2 option for creating fragment

Create fragment as Facelets
Create fragment as JSP XML 

Facelets- is default and official view handler for JSF pages, priviously JSP was used to view JSF pages but it didn't support all component so Facelets comes in picture under APACHE open source license. It supprts all UI component used by JSF (Java Server Faces).
Facelets was developed by Jacob Hookom in 2005.
If you create Facelets fragment in bounded taskflow, then taskflow must be dropped in a JSF page (parent page) not in .jspx (JSP XML ) page.
if you try to drop it into JSP XML page-

JSP XML- jspx is XML variant of JSP(Java Server Pages) to support XML document . JSP XML fragments are used in ADF inorder to support XML document and more powerful page validation techniques.
If you create jsp xml fragments in bounded taskflow, then taskflow must be dropped in a JSP XML(.jspx) page(parent page) not in JSF page.

Using Contextual Event in Oracle ADF (Region Communication)

Contextual event ,in simple terms is a way to communicate between taskflows.

Sometimes we have taskflow open in a region and have to get some values from that taskflow .

This scenario can be achieved by contextual event.

 

Contextual Event have two parts-

1. Publisher Event (Producer)- As button or any component that can raise event 
2. Handler Event (Customer)- that listens and process event published by producer

This tutorial is based on example developed on default HR schema of Oracle DB 11g

I have created two application and called first one in secod application as region.

• Create first application using Department table of HR schema and drag Department Name on page fragment, now create publisher event (follow steps) for Department Name .
• Select Department Name field in structure window and go to property Inspector select ContextualEvent
  click on green add icon and select event type and name for publisher event

 

• Select field value from Iterator Binding
  
• here you are done with publisher event or producer create a jar of this application in order to use it in second application.
• Now start Second Application that will handle and process this event, create a page and put an output text and set its value from managed bean
  
  
  
  
  
  

• Now create a event handler class to process published event and to make it available to page binding level , we have to create DataControl for this class.
  
  
  
  
  
  
  
  
• Right click on event class and Click on CreateDataControl.
• Now add this method binding to page so that it can be accessible from page binding

• Now drag and drop taskflow from jar library on page as region by this published event will also be available to page
  

  
• Now go to page binding and goto ContextualEvents tab ,click on subscribers tab and click on add icon this will open a popup window ,click on search button , it will show available publisher event, now select event and goto handler search option and select function that you have previously added in page binding
• Give consumer parameter name same as event handler function

Phone Number custom validation using Regular Expression in ADF and Java

Regular Expression (REGEX) is the best method to validate phone number. emailId, name in Java.
Here I have written this validation code for phone number using Regular Expression and Java code to use this in an Oracle ADF Application.

                }
            }
            //if openB=0 then no. of closing and opening brackets equal || opening bracket must always come before closing brackets
            //closing brackets must not come before first occurrence of openning bracket
            if (openB != closeB || closeFg == true || (phnNo.lastIndexOf("(") > phnNo.lastIndexOf(")")) ||
